	This routine sends new digital alarm block nominal and mask values
	for a device.

	device_index	device index of interest
	nominal		nominal value
	mask		mask value
	[start_block]	starting block to send (starts at 0)
			(default is 0) (maximum is DIO_MAX_ALARM_BLOCKS - 1)
	[num_blocks]	number of blocks to send (default is 1)
			(maximum is DIO_MAX_ALARM_BLOCKS)

	This function returns ACNET status values as follows:

	OK			success
	DIO_BADARG		invalid alarm block requested
	otherwise		ACNET format error

	This function requires the following include files:

	diolib_h, acnet_errors_h
